A new mixed meshless approach using the interpolation of both stress and displacement has been proposed for the analysis of plate deformation responses. A kinematic of three dimensional solid is adopted and discretization is performed by the nodes located on the upper and lower plate surfaces. The governing equations are derived by employing the local Petrov-Galerkin approach. The approximation of all unknown field variables is carried out by using the B-spline interpolation and the Moving Least Squares functions in the in-plane directions, while linear polynomials are applied in the transversal direction. In order to eliminate the thickness locking effect, the hierarchical quadratic interpolation of the transversal displacement component through the thickness is used. The shear locking effect is efficiently suppressed by the interpolation of the stress field independently from the displacement. The numerical efficiency of the derived algorithm is demonstrated by the numerical examples.
